RouterWise: Joint Resource Allocation and Routing for Latency-Aware Multi-Model LLM Serving

Adel N. Toosi, Christopher Leckie, Gholamreza Haffari, Hossein Hosseini Kasnavieh

Jointly tuning GPU shares and routing fractions across models raises output quality by up to 87 percent while meeting a fixed latency target.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

even on the same GPU cluster, achievable output-quality score can vary by up to 87% across retained setups, highlighting that resource allocation is a key determinant of routing performance.

C2weakest assumption

The latency models obtained from system profiling accurately predict end-to-end latency when the routing policy induces a particular load on each model under a chosen resource allocation.

C3one line summary

Joint resource allocation and routing for multi-model LLM serving can produce up to 87% variation in achievable output quality across setups on the same GPU cluster.
